    • BRIEF DESCRIPTION OF THE DRAWINGS
  • The invention is explained in greater detail below with reference to preferred exemplary embodiments. In the drawings:
  • FIG. 1 shows a schematic illustration of a plug connector in accordance with a first exemplary embodiment according to the invention;
  • FIG. 2 shows a schematic illustration of a plug connector in accordance with a second exemplary embodiment according to the invention, and
  • FIG. 3 shows a schematic illustration of an angled sheet-metal portion of the plug connector from FIG. 2.
    • BEST MODE FOR CARRYING OUT THE INVENTIONS
  • FIG. 1 shows a schematic illustration of a plug connector 1 according to the invention for supplying power to an electrical load (not illustrated), for example a lamp for airfield illumination. The plug connector 1 has a contact spring 2 for optionally accommodating a contact blade (not illustrated) of a power supply line of the load and has a contact blade 4 for electrical connection to a contact spring (not illustrated) of a power supply line of the load. The plug connector 1 also has a conductor connection 6 for connection of a connection line 8. According to the invention, the contact spring 2 and the contact blade 4 have a substantially identical insertion direction. As a result, the plug connector 1 permits simple cable routing together with a reduced space requirement since the connection line 8 of the plug connector 1 or the power supply line of the lamp (not illustrated) for making contact with the plug connector 1 does not have to be bent and led back. In the illustrated exemplary embodiment, the contact spring 2 and the contact blade 4 run approximately parallel to one another and are formed opposite the conductor connection 6. The contact spring 2 has two spring tabs 10, 12 which are opposite one another and form an accommodation region 16, in which the contact blade (not illustrated) of the power supply line can be clamped, with a rear wall 14 of the contact spring 2. The spring tabs 10, 12 are bent inward in such a way that edge sections 18, 20 run approximately perpendicular to the rear wall 14 of the accommodation region 16. To this end, sections of the spring tabs 10, 12 are of curved design. The spring tabs 10, 12 are arranged on that side of the contact spring 2 which faces the contact blade 4, with the result that an extremely compact design of the plug connector 1 is achieved. To improve the clamping action, bearing projections (not illustrated) for the contact blade of the power supply line are provided on the rear wall 14. The contact spring 2 and the contact blade 4 have a common connecting section 22 which forms a stop face 24 for limiting the insertion depth of the contact spring and/or of the contact blade of the power supply line. The contact blade 4 is provided with an eyelet 26 approximately in the center and is of plate-like design with a rectangular base area 28 with chamfered corner regions. In order to make electrical contact with a stripped end 30 of the connection line 8, the conductor connection 6 is formed as a pinched connection (crimped connection) with two wire claws 32 which are opposite one another and are pinch-connected to the end 30 of the connection line 8. In order to relieve the strain on the connection line 8, the conductor connection 6 is provided with two insulation claws 34 which surround a circumferential section of the insulation sheath of the connection line 8 and are pressed against said connection line. The contact blade 4, the contact spring 2 and the conductor connection 6 are preferably of integral design for production reasons. A plug connector 1 of this type can advantageously be produced as a stamped and bent sheet-metal part, for example.
  • In one exemplary embodiment (not illustrated), the connection line 8 is connected to the plug connector 1 by means of an insulation-displacement contact.
  • According to FIG. 2, which shows a plug connector 36 in accordance with a second exemplary embodiment according to the invention, the edge sections 18, 20 of the spring tabs 10, 12 are bent toward one another in a curved manner and run approximately parallel to the rear wall 14 of the accommodation region 16 in this exemplary embodiment. Furthermore, in comparison to the above-described exemplary embodiment, the spring tabs 10, 12 are arranged on that side of the contact spring 2 which is averted from the contact blade 4 in this variant. In order to make electrical contact with the connection line 8, a conductor connection 6, which is in the form of a connecting sleeve 38, is provided on the rear face of the common connecting section 22 of the contact spring 2 and of the contact blade 4. The connecting sleeve 38 may be in the form of a pinched connection or a welding or soldering sleeve for accommodating the connection line 8.
  • As can be seen particularly in FIG. 3, which shows a plan view of an angled sheet-metal portion of the plug connector 36 from FIG. 2, the contact spring 2 and the contact blade 4 are connected via the common connecting section 22. Two opposite free edge sections of said connecting section are provided with tabs 40, 42 for forming the connecting sleeve 38 (see FIG. 2).
  • The plug connector 1, 36 according to the invention is not restricted to the illustrated embodiment of the contact spring 2 and the contact blade 4, but instead the plug connector 1, 36 can be provided with various contact spring and contact blade forms which are known from the prior art.
  • This document discloses a plug connector 1, 36 for supplying power to an electrical load, in particular a lamp, comprising a contact spring 2 for electrical connection to a contact blade, a contact blade 4 for electrical connection to a contact spring, and comprising a conductor connection 6 for connection of a connection line 8, wherein the contact spring 2 and the contact blade 4 have a substantially identical insertion direction.
